APPARATUS FOR THE MANUFACTURE F AERATED AND MTNERAL WATERS.

4SPECIFICATION' forming part of Letters Patent No. 301,919, dated July 15, 1884.

Application lled Juno 25, 1883. (Nomodel.) v

l subject of the Queen of Great Britain, residing at New York city, in the State of New York,

have invented certain new and useful ImprovementsY in Apparatus for the Manufacturel of Aerated and Mineral Waters, of which the following is a specification.

My invention relates to apparatus designed for the production of articial mineral and aerated waters. It is myobject to produce an efficient and simple apparatus of this kind, one in which there will be a thorough and uniform incorporation of the gas and liquid, which will work continuously, delivering without intermission the requisite `quantity of aerated liquid to the bottlers, and which will have a greater and more varied capacity for work than has been the case heretofore in machines or apparatus of like type.

The nature of my improvements and the manner in which the same are or may be 'carried into effect can best be explained and understood by reference to the accompanying drawings, in which I have represented an apparatus embodying my invention in its preferred form.

Figure lis a Afront elevation of the apparatus. Fig. 2 is a side elevation of the same with the condensers and liquid-supply tanks removed. Fig. 3 is a vertical central section of the pump-cylinder and valve-boxes. l Fig. 4 is a longitudinal central section of one of the condensers. Fig. 5 is a longitudinal central section of the equilibrium-valve hereinafter described.

The power for driving the pump lof the aerating apparatus proper can be obtained from any convenient source. In the present instance 'it is obtained from a steam-engine mounted in or on the same frame, yA,'that car; ries the aerating apparatus. The engine is of ordinary vertical type, having steam-cylinder 1, piston and piston-rod 2, connectingrod 3, crank-shaft 4, ily-wheel 5, eccentric and eccentric-rod 6, and slide-valve 7. On the crank-shaft is a pulley, 15, to drive any machinethat may be desired, and also a toothed pinion, 8, which gears with a spur-- wheel, 9, fixed uponthe pump-shaft 10. Pinion 8 is mounted to slide on a key-bed on the devices should be combined with said pinion. The pinion 8 is smaller than the spur-wheel 9, so that the engine-shaft will make several revolutions to every one of the pump-shaft. In the arrangement shown in the drawings the rate of-movement is as three to one, the object being toinsure a powerful, uniform, positive movement of the pump. When the pump is not in action, and the pinion Sis out of gear with the pump-shaft, the engine can i be used to drive anyv other machinery in the establishment where the apparatus is set up.

The pump'is composed of a cylinder, B, containing a piston, C, composed of two cupped leather washers held between two metallic heads or disks, as indicated in Fig.`

3. The piston-rod D passes down through a stuffing boX in the lower head of theV cylinder, and is Vmade fast to the bottom cross-head of a verticallyreciprocatory frame, E, supported in, suitable guides, and having jointed to its top `cross-head the connecting-rod F4 fromthe crank of pump-shaft l0. At each end of the pump-cylinder is a valve-box, G and H, the two being counterparts of one another.- In each valve-box an inlet puppetvalve, a, controls the supplyof gas and liquid'.

drawn into the pump through the inlet-pipe' b, which communicates on the one hand withl gas-pipe c, leading from a gas-holder or other suitable source of gas-supply, and on the other hand with liquid-pipe d, leading from a its own system of supply and discharge pipes independent of and separate from that of the other valve-box, and that each can be regulated independently of the other. Thus from one end of the cylinder one condenser can be suppliedwith gas and liquid in given proportions and at a given pressure, while from the other end of the same pump-cylinder the other condenser can be supplied with gas and liquid of an entirely different character from IOO the other, in different proportion, and at a different pressure. In other words, the same pump will sufce under this arrangement to run at the same time two distinct sets of condensers for waters of entirely different charaeters.

Each condenser J is like the other, so that a description of one will answer for both. It has by preference the form of a cylinder closed at the ends by heads bolted thereto, through stuffing-boxes on which heads pass the agitator-shaft K, which is driven by belt and pulley ll from any suitable source of power-as, for instance, from pulley l2 on the pumpshaft. The condenser is provided with any ordinary or suitable safety-valve, g, a pressure-gage, h, and a water-gage, fi. It is also provided with a device, j, which I term a regulating-valve, and which will be hereinafter referred to. The agitator-shaft is provided with a suitable arrangement of fans or breakers. That which I prefer and which I have found most effective is plates k, fixed on the shaft and formed with diagonal slots Z, those in the one plate slanting in a direction opposite to those in the other. By this meansI cut the liquid and produce a thorough intermingling of it with the gas. To still further insure the thorough intermixture of the gas and liquid, and at the same time also to maintain the aerated liquid in a still andquiet state at the point where it is drawn off from the condenser to the bottling machines, I extend the agitator-blades or breakers part way only ofthe length of the condenser, and divide this portion of the condenser from the other by a partition, m, in which are formed at a suitable height, preferably somewhat above the axis, one or more holes or openings n. The gas and liquid entering the condenser through pipef are worked together and mixed in the agitator chamber proper, where the liquid must accumulate until it can overflow through the partitions into the delivery-chamberp beyond, whence it is drawn off to the bottlingmachines through the draw-off pipe o.

The regulating-valve 7`, hereinbefore referred to, is located on the discharge-chamber p. Its construction can be considerably varied; but Iprefer to makeit as shown in Fig. 5. Its shell is screwed into the condenser, so as to have communication with the interior of chamber p,- and it is loca-ted at a height thereon which is about that of the normal level of the charged liquid in said chamber. In the interior of the shell is formed a conical valve-seating, r, against which bears a plug, s, of rubber or other suitable elastic material, which is pressed up against the seat by the hollow externallyscrew-threaded stem t. rIhis stem surrounds the rubber plug and screws into the valve shell or case, and by means of it the bearing of the rubber valve-plug against the seat can be adjusted and regulated so as to permit the rubber to yield and permit the escape of the contents of chamber p at any desired degree of internal pressure; A waste or return pipe,

c, carries off the liquid that may escape through the valve. The valve is set to open when the pressure exceeds a predetermined limit, and to thus relieve the chamber of abnormal pressure.

It frequently happens that on'e or more of the bottling-machines supplied from the condenser slacken speed or stop bottling entirely. In this case the condenser becomes oversupplied or overcharged, and the delivery-chamber frequently contains an excess of gas as compared with liquid, or the reverse. The regulating-valve being set to yield to predetermined pressure, (which of course is less than that at which the ordinary safety-valve, g, is set to yield,) relieves the condenser of its oversupply, and, being placed at the normal level of the liquid in the chamber p, will, in thus relieving the condenser, discharge gas orliquid, according as there may be asuperabundance or excess of one or the other.

I remark that each water-supply tank I has a float-valve, w, which will automatically open to admit fresh supply of water as soon as the water in the tank falls below a certain level. This, however, is a known arrangement and requires no further explanation.

Having described my improvements and the best way known to me of carrying the same into effect, Istate in conclusion that I do not wish to be understood as restricting myself to the special details of construction herein shown and described in illustration of my invention, for the same can be considerably varied without departure therefrom; but l Vhat I claim as new and of my invention 1sl. In an apparatus for the manufacture of aerated waters, the combination of the pumpcylinder and its piston, valve-boxes-one for each end of the pump-cylinder-provided each with a system of supply and discharge pipes independent of and separate from the other, and condensers, whereby each system draws its own supply of gas and liquid in regulable quantity, and discharges the same in mixed condition into the appropriate condenser, substantially as and for the purposes hereinbefore set forth.

2. The combination, with the condenser and agitator, of a perforated partition separating the delivery end of the condenser from that portion of the same which contains the agitating or mixing appliances, substantially as hereinbefore set forth.

3. The combination, with 'the condenser, of the regulating-valve applied to the delivery end or chamber of said condenser, under the arrangement and for operation substantially as and for the purposes hereinbefore set forth.

In testimony whereof I have hereunto set my hand.
